javascript - Screeps:计算 body 的构建成本

Question

玩游戏的时候screeps.com我想计算 build 所需车身的成本。请参阅下面的尝试，其中 cfg.body 是 bodypart 数组，例如[Game.ATTACK, Game.MOVE, Game.WORK, Game.CARRY, Game.MOVE]:

var buildCost = 0;

for(var bodypart in cfg.body){
  switch(bodypart){
    case "MOVE":
    case "CARRY":
       buildCost+=50;
       break;
    case "WORK":
       buildCost+=20;
       break;
    case "HEAL":
       buildCost+=200;
       break;
    case "TOUGH":
       buildCost+=20;
       break;
    case "ATTACK":
       buildCost+=80;
       break;
    case "RANGED_ATTACK":
       buildCost+=150;
       break;
  }
  console.log(bodypart + " costs " + buildCost);
}

当打印 bodypart 到控制台时，它显示索引(0、1、2、3、...)并且 buildCost 保持为 0。

也许 BODYPART_COST 常量以前不可用，但有了它您可以这样做:

function bodyCost (body) {
    return body.reduce(function (cost, part) {
        return cost + BODYPART_COST[part];
    }, 0);
}
